ASTM B423 Incoloy 825 Seamless Tube Specification

Nickel based alloys are very useful materials for the manufacture of high quality tubing products. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high temperature applications.

Product Name: ASTM B423 Incoloy 825 Seamless Tube

Our specialized process for seamless tubing manufacturing begins with either an extruded hollow tube or a solid bar drilled to our exacting specifications. The material is then reduced in size a number of times through various cold working techniques until it reaches the specific size, tolerances, and temper required by our customer. After each cold working cycle the tubes are cut, cleaned and heat treated in preparation for the next cold working step. Seamless tubes can be created in a variety of different sizes and shapes from a wide range of alloys.

ASTM B423 Incoloy 825 Seamless Tube are ideal for tubes used in some of the most demanding applications

Our ASTM B423 Incoloy 825 Seamless Tube, seamless and welded drawn tubes range in size from under 0.010” (1/4 mm) right up to 1.5” (38.1mm) outside diameter, and we can produce finished wall thicknesses down to less than 0.002” (0.05 mm) through to 0.150” (3.8mm).

You can order straight lengths of tubing from us up to 45ft (14m) long or coiled tubes up to 3,200ft (975m) in length.

ASTM B423 Incoloy 825 Seamless Tube quality certificates

ASTM B423 Incoloy 825 Seamless Tube delivered with a 3.1 certificate. we can perform the tests required to issue a 3.2 certificate, or a CMTR in accordance with the ASME III Code.

ASTM B423 Incoloy 825 Seamless Tube Packaging & Shipping

Our staff has extensive experience in export documentation,packaging, and finance. We have found that the biggest key to a successful export transaction is communication.

825 is an all-purpose project alloy, have good corrosion resistance of the acid and alkali metal property in both oxidation and reduction environments. High nickel content made it with effective stress corrosion cracking resistance performance. 825 have excellent corrosion resistance in different kinds of media, such as sulfuric acid, phosphoric acid, nitric acid and organic acid, alkali metal such as sodium hydroxide, potassium hydroxide, and hydrochloric acid. A variety of media corrosion of nuclear-burning dissolver show 825 high integrated prpperty, like sulfuric acid, nitric acid and potassium hydroxide are all dealing in a same device.

Incoloy 825 Application field：

825 widely use in many kinds of industry field that the working temperature no more than 550°C.
